Brown, Z. Warhaft, and Greg A. Voth<br/>We measure acceleration statistics of neutrally buoyant spherical particles with a diameter 0.4<d/η<27 in intense turbulence (400<R_{λ} <815). High speed cameras image polystyrene tracer particles in a flow between counterrotating disks. The measurements of acceleration variance ⟨a^{2} ⟩ clearly resolve the transition from the tracer like behavior of small particles to the much smaller accelerations of large particles. Two models of this transition from small to large particle behavior are critically examined. For d>5η, ⟨a^{2} ⟩ decreases with the diameter as d^{-2/3} , in agreement with inertial range scaling arguments. Consistent with earlier work, we find that the scaled acceleration probability density functi...<br/>[Phys. Rev. Lett. 103, 194501] Published Thu Nov 05, 2009 Rachel D. Brown, Z. Warhaft, and Greg A.

We introduce here the concept of an optical nanocircuit board, constituted of a layered metamaterial structure with low effective permittivity, over which specific traces that channel the optical displa...<br/>[Phys.

This approach enhances the laser intensity and counteracts ionization-induced defocusing, extending the cutoff photon...<br/>[Phys. Rev. Lett. 103, 143901] Published Tue Sep 29, 2009 P. Arpin, T.

Such a mechanism has never been demonstrated experimentally. Using small cylinders as vortex generators to create streamwise counterrotating vortices, we show, through ...<br/>[Phys. Rev.
